HARROW TOOTH Filed July 9, 1929 In vnior Samuel .Lemmona Patented Aug.19, 1930 1 UNITED" srrss IPATENI oFFIcE SAMUEL C. LEMMONS, OF CEDARHILL, TENNESSEE ASSIGN OR F ONE-HALF T0 JAMES L. SPARKS, OFRUSSELLVILLE, KENTUCKY HARROW Too'rH Application filed July 9, 1929.Serial No. 376,901..

v1de an improved tooth for harrows, wherein the tooth is so formed as toprovide a suitable attaching portion adapted to grip the frame of theharrow so that said tooth may be rigidly maintained on said harrowframe, the

connection between the tooth and the harrow frame being strong,positive, durable and otherwise well adapted for maintaimng the tooth ina stationary and fixed position upon the frame.

Other objects and advantages of the invention will become more apparentdurlnga study of the following description taken 1n connection with theaccompanying drawlngs,

wherein:

Figure 1 is a side elevation of my improved harrow tooth showing thesame attached to the frame of the harrow, the frame being shownfragmentarily.

Figure 2 is a detail perspective view of the harrow tooth per se.

With reference more in detail to the drawings, it will be seen that havedesignated generally by the reference character 5,v a harrow frame towhich my tooth is adapted to be applied, said harrow frame being hereinshown merely for the purpose of fully illustrating the application of myinventlon, consequently the frame being shown merely fragmentarily.

In the present embodiment of my inven tion, it is intended to form thetooth generally designated by the reference character 6 of a singlestrand of wire, malleable steel or other strong and durable material ofsuit-able length. In forming the tooth therefor, the wire at one endthereof is offset as at 7, the offset portion being flattened to providethe tooth or penetratingpoint 8, which point is shown as ofsubstantially diamond shape in configuration. The material forming thetooth 8 is extended rearwardly of the toothso as to provide the shank 9.The shank 9 at Its opposite end is offset as at 10 and the materialforming the shank at this offset portion is looped upon itself toprovlde an attachlng eye 11. Continuing from the eye 11, the materialthen forming the tooth is extended rearwardly as at 12 and then bent atright angles as at '13, and again as at 14, in parallelism with the part12, thus forming a lateri,

ally extending substantially U-shaped bracket herein designatedgenerally by the -reference character 16. I The portions 12 and 13 maybe termed the legs of the'U-shaped bracket and it is to be noted, inthis connec-- tion, that the-leg 14 terminates in an upstanding abutment15.

i In applying the tooth to the frame 5 of the harrow, it will be seenthat the eye 11 at the upper end of the shank 9 is disposed to one sideof the frame 5 and that a bolt or suitable fastening element 15 may bepassed through the eye and the frame 5, and a lock nut18 threaded on thebolt for securing the eye portion of the shank securely against the saidface vof the frame. Obviously then, the U- shaped bracket 16 will extendtransversely of the frame 5, to engage the bottom face of the frameandthat the leg 14 of the bracket will project beyond the opposite face ofthe frame result that the same is disposed upon the crown portion 13 ofthe U-shaped bracket 16 between the eye 11 and'the upstanding projection15 andthat the shank 9 will extend downwardly and forwardly of theframe, all of which is clearly shown in Figure 1.'

" From the foregoing then, it will be seen that I have provided a strongand durable tooth which can be readily and easily secured to the toothsupporting frame of the harrow and the tooth being equipped toformintegral therewith suitable attaching means, whereby the frame may besecurely gripped by the upper end of the toothlso as to prevent anyuntoward movement of the tooth upon the frame, and at the same timeretain the tooth in a strong and rigid fixed relation to the frame. I

' Even though I have herein shown and described the preferred embodimentof my invention, it is to be understood that the same is susceptible tochanges fully comprehended by the spirit of the invention and the scopeof the appended claims.

What is claimed is:

1. In combination with a harrow, wherein the same comprises a toothedsupporting frame, a tooth comprising a penetrating point and a shankrising from said point, said shank being provided at its upper end witha loop extension adapted to be disposed on one side of the toothsupporting frame, and that portion of the shank adjacent said loopedextension extending laterally for engagement with the under face of theframe, and the laterally extending portion of the shank terminating inan upstanding projection adapted for engagement with that side of theframe opposite to the side of the frame against which the loopedextension is disposed.

2. In combination with a harrow, wherein the harrow comprises a toothsupporting frame, of a-tooth comprising a shank portion terminating atone end in a penetrating point, said'shank at its opposite end beingprovided with a substantially U-shaped bracket, one leg of said bracketmerging into the shank at the opposite end of the shank and adapted toengage the tooth supporting frame adjacent one face of the frame, andthe other leg of said U-shaped bracket terminating in an. upstandingprojection adapted to engage with the opposite face of the frame.

3. In combination with a harrow, wherein the harrow comprises a toothedsupport- 7 face of the frame, and said laterally extend ing portionterminating in an upstanding projection adapted to abut that'side of theframe opposite to the side of the frame against which the looseextension is disposed.

4. In combination with a harrow, whereinthe harrow comprises a toothedsupporting frame, of a tooth comprising a shank terminating at one endin a downwardly and forwardly inclined penetrating'point, said shank at.its opposite end being provided with a substantially U-shaped bracket,one leg of said bracket merging into an .eye at said-opposite end of theshank, said eye adapted for disposition against one side of the frame, abolt passing through said eye and said frame, and the other leg of saidU-
